Standard 3bet here is 3x the open in position, make your 3bet at least $0.18.
The flop donk bet is probably not a set - an utg open/call 3bet isn't going to hit this flop well. It's probably not KK+ either, since those hands would usually have 4bet pf. This line is consistent w 99-QQ at microstakes.
I'm w everyone else, fold, the flop betsize is too large to call and hope for one of our six outs. If the flop betsize were, say, 1/3 to 1/2 psb, I will frequently raise it assuming I have some FE (we 3bet, he'll have to be worried we have KK+) and have 6 outs - but he looks commmitted (i.e., we don't have FE).
